A measurement of the normal retrogastric space in Korean adults

The radiologic measurement of the normal retrogastric space and retroduodenal space was established in 178normal adults. This procedure has great value in detection of pancreas body and tail enlargement. Using rightlateral recumbent, left lateral erect and translateral view, the following distances were measured 1) from cardiato the anterior margin of vertebra 2) from pars media to the margin of vertebra 3) from antrum to the margin ofvertebra 4) from descending duodenum to the margin of vertebra Good correlation exists between the trueretrogastric thickness and patient weight, but none between the true retroduodenal distance and patient weight.The most frequent impression upon the posterior gastric wall was due to distention of the large bowel in theregion of the splenic flexure.
